Catherine (Burkel) Grammel (1845 - 1912)*

According to the immigration documentation that I have accepted as the most likely match for Sebastian Burkel, he had a single child before he and his wife, Catherine, emigrated to the United States in 1847. That child, a daughter also named Catherine, is listed as two years old in December of 1847 which would put her birth date in 1845.
Catherine is listed on the census in 1860 as 15 years old. By the time of the next census, in 1870 she is no longer listed with the family. She would have been 25 years old by then.
I had assumed that she had been married at some point between 1860 and 1870. It was not until this past year that my assumption was proven correct by the release of  more Michigan marriage listings on Ancestry.com.
On 9 Nov 1869 Catherine Burkel was married to Louis "Grimel" of Royal Oak, MI. They were wed at St. Mary's Church. Catherine's brother Anthony "Anton" Burkel was a witness along with Josephina "Schobe". The place of birth for both Catherine and Louis is listed as France, and Louis is listed as a Farmer.

With each year the census documents include more and more information. That is why finding the marriage information for Catherine was so important. Without her married name I lost track of her after 1860. I had no way to tell what had happened in her adult life, or if she even survived past the age of 15.
On the 1870 census "Kate" and Louis "Gremmal" are listed as living in the township of Royal Oak. Their estate was worth a modest $1400.00 (Compared to Sebastian's $2400.00). They both have parents of foreign birth. By 1880 "Catarina" and "Loui Grammel" were listed as living in Detroit, Wayne, MI. Both of them list their own, plus their mother and father's birthplace as France. Loui's occupation is listed as "Dealing in Wood" which likely meant he was a carpenter. Catherine's occupation is listed as "Keeping House". (Interesting that they considered this an occupation in 1880!) There are no children listed.

In the census from 1900 Catherine  "Kate" is listed as 55 years old, her birth year is 1845 and she has been married to Louis for 31 years. They lived in Royal Oak, MI. According to the census, Louis immigrated in 1854 and became a naturalized citizen. Catherine's immigration year is listed as 1848 and she is not listed as a naturalized citizen. Under "mother of how many children" there appears to be a very faint number 1. Under "number of those children living" there is a very clear "0". The nativity of Catherine, Louis and both of their parents is listed as France. They can both read, write and speak English. Louis owns his home "free" meaning it is not mortgaged. Neither of them have an occupation listed.
By 1910 "Katherine" and "Loius Grammel" were still living in Royal Oak. Most of the information is similar to, but slightly different from what was listed in previous years. The nativity of Louis, Catherine, and their parents is now listed  as "France Ger" instead of France. Catherine's immigration year is listed as 1865. Neither of them are listed as having an occupation, Louis is listed as living on his "own account". They both speak English and can read and write. In the 1900 census, Louis is listed as owning his house, now he is listed as owning a home that includes a farm. There is a space for veteran of the Civil War, and in this space there is a very faintly written "19" for Louis. There is also a "9" in the space for blind and an "X" in the space for deaf and dumb. On this census it is more clear that Catherine had at least one child, and it did not survive.

Census for Louis and Catherine Grammel, 1910

After the 1910 census I have not been able to locate any further information for Catherine. Louis was married again on 6 Nov 1913 to Mary Bower of Macomb Co. My guess is that Catherine passed away sometime between 1910 and 1913.
There is a death certificate for someone named "Esther Gremmel" of Royal Oak. She was born in 1846 in France. Her mother is listed as Catherine "Shope" and her father is listed as John Rusie, and he was born in Michigan. I feel like, even though some of the information does not match up, this might be Catherine. Sometimes the records don't always match. For instance, the marriage record of Louis Grammel and Mary Bower seems to be attached to the wrong "next" page. (See below) As you follow across the page, it looks like the lines do not match up. I am wondering if this could be the reason that there is some matching and non-matching information in the death record for "Esther". For instance, it seems odd that she would have been born in France, but her father was born in Michigan.
So, for the death record the last name, residence, mother's first and last name, birth place and year are all a close match. Since Louis remarried in 1913 I have accepted (for now) that Catherine passed away in 1912.
